Added a verb to beds, bedsheets and sub-objects to allow them to be flipped to face the opposite direction (if they have directional sprites available). This applies to chairs too, because why not. If it's possible for me to just not display the verb for non-flippable subtypes, let me know how!
Also swaps out some beds on the Stellar Delight to face the other direction so that their pillows are against the wall.
Added pillows, which can be placed my clicking themselves or combined with identical pillows to build a pillow pile. Pillow piles are in two parts, a front and back, which can be disassembled by clicking on each with an empty hand. You can buckle to either part of the pillow pile.
The sprites were ported from skyrat, with some additional colours added. Currently only the square pillows and large piles are being used. There isn't currently a way to acquire these normally, only admin spawn at the moment, but I intend to add one soon.
